Flash Cards 5

Question 1

What is sexual reproduction?

Answer 1

When Two Parents (male, female)
daughter cells are a mixture/combination of genes.
-1 parent to 4 daughter cell

Question 2

What does sexual reproduction do?

Answer 2

Produces variety (variation) allows the organism to be better adapted to a changing environment and thus a greater survival advantage.

Question 3

What is Hemophilia?

Answer 3

Slow or no blood clotting ; recessive allele

Question 4

What is the male sexual Reproduction

Answer 4

Interphase cytokinesis
(99% life) 23 chromosomes
1 4
46 chromosomes 2nd cell division
Parent cell 4 daughter cells
1st cell division

Question 5

What is the female Sexual Reproduction?

Answer 5

Interphase
1
1st cell division
46 —> doubled 96 chromosomes
Parent Cell

Cytokinesis
4
2nd cell division
23 chromosomes
4 daughter cells

Question 6

What is cell division (mitosis)?

Answer 6

Cell division is mitosis
Interphase
1
1st cell division
46 ——> doubled 96 chromosomes
parent cell

Cytokinesis
2
1st cell division
46 chromosomes
2 daughter cell

Question 7

What does cell division do?

Answer 7

Cell division glows (embryo, fetus, infancy, –> adult hood) and repair /maintenance of an organism.

Question 8

What is asexual reproduction?

Answer 8

1 parent / 2 daughter cells
Parent/ daughter cells identical appearance (genes) Parent / daughter cell same number of chromosomes.

Question 9

What is mutation?

Answer 9

Mutation is the change in the DNA code.

Question 10

What does Good/ Beneficial do?

Answer 10

Helps an organism to better adapt to its environment.

Question 11

What is neutral?

Answer 11

common ; neither helpful or harmful.

Question 12

What is Bad/Harmful?

Answer 12

Cancer ; no fertilization, dead, embryo, dead fetus, dead newborn ; genetic disorders

Question 13

What are the types of Mutations?

Answer 13

1. Substitution: Remove a base pair then in its place add a new base pair.
2. Deletion: Remove a base pair only
3. Addition : Add a base pair

Question 14

What are the causes of Mutation?

Answer 14

1. Chemical ; nicotine, gasoline
2. Radiation ; gamma rays
3. Genetic ; triple negative breast cancer
4. Fried Foods ; French fries, potato chips etc.

Question 15

What does variation do?

Answer 15

Allows a species to best adapt to a rapidly changing environment there by increasing the chance of survival.

Question 16

What is a Many Gene Trait?

Answer 16

Human height = 12 genes

Human Skin Color, human eye color.

Question 17

What is down syndrome?

Answer 17

extra copy of chromosomes 21 causing metal retardation.

Question 18

What is sickle - cell Anemia?

Answer 18

sickle shape red blood cells which can not carry much oxygen ; co dominant allele

Question 19

What is cystic fibrosis?

Answer 19

Mucus in lungs and intestines ; mutation of 3 base pair.

Question 20

What is karyotypes?

Answer 20

a picture of all chromosomes with form within a (body cell).

Question 21

What is Human Genetic Disorders?

Answer 21

A disease caused in whole or in part by chance in the DNA sequence away from the normal sequence.

Question 22

What is Meiosis?

Answer 22

Meiosis is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.
